If they are complete, I don't know why not. The only difference between the early and late are the top nuts and the size of the strut that goes through the bearing. If you R&R the whole strut intact, it should be very easy, fit perfect and take about 1/2 the time to do the job.
Sounds like a bargain suspension system. If you don't want it, sell to me!
